SUPPORT FOR E LECTRIC LAMPS.

srn'orfionirfoiv forming part of Letters Patent No. 657,502, datedSeptember 4, 1900.

Application filed January 6, 1900- Serial No. 612. (No model.)

To all whom it may concern:

Be it known that I, WILLIS A. SWAN, a citizen of the UnitedStates,-residing at Providence, in the county of Providence and State ofRhode Island, have invented certain new and useful Improvements inBrackets or Supports for Electric and other Lamps; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to adjustable brackets or supports for supportinglamps, being especially designed to support electric incandes: centlamps; and the primary object is to provide a support capable of avariety of adjustments, so that when in use 'over desks, tables, andother like places, where the position of the lamp requires to be changedat different times, the lamp may be quickly shifted-to any desiredposition and there supported without the necessity of the usualfastening devices.

Another object of the invention is to so constructthe bracket or supportthat its adjustment from one position to another will not stretch orinjure the conducting-wires of electric lamps. Other objects will becomeapparent upon a detail description of the invention. The inventionconsists, essentially, in the novel construction and general arrangementof the various parts of the device, as will be hereinafter more fullydescribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of thebracket or support supporting an electric incandescent lamp; Fig. 2, alongitudinal section of a portion of the bracket or support, takenthrough the bearings of two of the" joints; Fig. 3, a perspective viewof one of the bearing-bushings, and Fig. 4 a view showing the sect-ionsfolded together.

Referring to the several views, the numeral I indicates a rosette, ofany suitable design, which is adapted to be secured to the wall or otherdesired part of an apartment and is preferably provided with a tubulararm 2, projecting therefrom. The outer surface of the tubular arm tapersfrom its base toward its outer end for a portion of its length, theremaining portion being cylindrical and screwthreaded. J ournaled on thearm 2 is a yoke 3, the center of which is bored tapering to cor respondto the taper of said arm. A confining-nut 4 serves to hold the yoke onthe arm 2,- and in order to prevent the out from becoming accidentallyloosened the end of said arm is provided with a slot 7, into which isseated a tang 8 of a washer 9. The ends of the yoke are formed withtapering bearings 10 10, and fitting into each bearing is acorrespondingly tapered bushing 11, provided with a countersunk aperture12 and with two or more'pins 13, projecting from the inner face thereof,

the purpose of which will be hereinafter ex- 7 plained.

Thenumerals 14 14 indicate sections of tubing, which may be of anydesired length. To one'end of each section is secured a yoke 15,

the ends of which are formed with hubs 16.

These hubs are provided with a central screwthreaded aperture 17 andwith two or more holes 18. The other ends of the tubularsections areprovided with yokes 19 19, similar in all respects to the yoke 3. Thesaid ends are made tapering, as shown in Fig. '2, and are internallyscrew-threaded to receive a short screw-threaded tube 20. The yokes 19are journaled on the tapering end of the sections and are confinedthereon by'nuts 21, screwed onto the ends of said tubes. Washers similarto the washers 9 are employed to prevent the nuts from turning andbecoming loose, and the end of each tube 20 is provided with a slot 22,into which the tang of the washer enters. The sections are joinedtogether by inserting screws 23 into the countersunk apertures 12 andscrewing them into the screwthreaded apertures 17. "In joining thesections together the pins 13 of the bushings 11 enter the holes 18 inthe hubs of the yokes 15, thus securing the bushings to the hubs andcausing the turning movement to be on the bushings and not on thescrews, which construction prevents the screws from becoming spectiveends of the yokes 3 and 15 are brought together and the bushings 11inserted into the bearings 10, with the pins 13 entered in The sections1 IOO 7 the holes 18 in the hubs of the yoke 15; The

I screws 23 are then passed through the bushings andscrewed intoitheapertures 17.

j Hinged to the yoke 19', journa1ed on the free end ofithe outersection, is a yoke24,

lamp and,'by reason ofthe peculiar construc- .tion of the jointsof saidsectio s, are n ini jured by the fit-arioiusadjustments to which thebracket or support may be subjected.-

' ber of sections may beemployed, as desired.

By'journalingLthe yoke'3 on thearm 2 and thefyokes 18 on the sectionsvarious adjustp: ments other. than those permitted. 'by the j hingedjoints may be obtained, and byn' akj-z ing thebearings'taperinglostwear'maybe taken up and' the connecting parts kept tight,

thus insuring the support remaining in any 1 position to which it may beadjusted until changed.
